BOSTON – It took the Boston Bruins five years to score a power-play goal in the playoffs against the Montreal Canadiens.

They needed a mere 32 seconds to do it again.

Reilly Smith and Jarome Iginla scored on back-to-back man advantages to help the Bruins snap an 0-for-39 postseason power-play drought against Montreal and beat the Canadiens 4-2 on Saturday.

The victory in Game 5 gave Boston a 3-2 lead in the best-of-seven Eastern Conference semifinal series and a chance to eliminate its Original Six rival in Montreal on Monday.

Carey Price made 26 saves for Montreal. Brendan Gallagher and P.K. Subban scored for the Canadiens, who need a victory in Game 6 to force the series back to Boston for a seventh game Wednesday.

Carl Soderberg and Loui Eriksson also scored for Boston. Tuukka Rask stopped 29 shots, extending his shutout streak to 122 minutes, 6 seconds before Gallagher scored to make the score 3-1 on a power play with 5:21 left in the second period.

The Bruins had not scored a power-play goal in the playoffs against Montreal in 14 games, dating to 2009.

“I think our power play wasn’t effective the first period,” Boston coach Claude Julien said. “We had a little chat after the opening period about turning up the intensity. Then we scored the two goals, and the power play was huge.”

Anaheim evens series

LOS ANGELES – John Gibson made 28 saves in his dynamic league playoff debut, captain Ryan Getzlaf had a goal and an assist, and the Anaheim Ducks beat Los Angeles 2-0 to even their West semifinal series at two games apiece.

Devante Smith-Pelly also scored in the first period and Corey Perry had two assists for the Ducks, who bounced back from two losses at home with consecutive victories at Staples Center.

The Ducks won despite being outshot 28-14.

Anaheim started its third netminder in three games with the dramatic entrance of Gibson, a 20-year-old American widely considered the best goaltending prospect in hockey.

Gibson, the youngest goalie to record a shutout in his NHL playoff debut, said, “I think there’s always nerves, but you’ve always got to learn to control them. After the first five minutes, I settled down.”
